ardour2 not working on G4 Titanium Tiger 10.4.7

Hi,
I've searched and asked for a way to solve the problem I have.
Ardour 2, Jack and QJackCtl, X11's and Tiger 10.4.7

I start QJackCtl, and launch Ardour, X11 opens up, Ardour icon is on the dock but nothing else happens. Icon stopped on the dock, no menu or anything, after 5 minutes it opens up.
Why is taking so much? any help?

Could that be: conflictive plug-ins, X11 not working properly, old versions of jack?
